WHEEL-RIM.

Specification of Letters Patent,

ing pneumatic tires upon a wheel and the object of theinveiition is toprovide a rim which may be quickly and easily detached from the tire andwhich will be held against collapse while being'placedvupon the wheel.The invention `is illustratedin the accoinf panying drawings, in which-Figure 1 4is a` side elevation of a wheel 'with my improved rim appliedthereto;

Fig. 2 is a detail perspective view of the parts of thev riin showingthe saine separated; `i .p

Fig. 3 is an enlarged detail plan view of the locking joint.

Figs. 4 and 5 are transverse sections show* ing different forms of rimsand tires.

`The Wheel 1 maybe of the usual or amI 'preferred construction andtheriin constituting my invention may be att-ached to the wheel by 4anyconvenient or preferred-ii'ieans, the drawing showing lugs or plates 2secured at intervals to the felly of the wheel and projecting over theedge of the rim 3 to prevent lateral ,movement of the saine.

The riin 3 consists of a pluralityA of vsections 4, `5, 6 and 7 whichare connected at their meetingr ends by hinges so that they may befolded together t0 be quicklyl removed from 4the tire when it isnecessary to repair the 'f tire or substitut-e a new tire for a worn outtire.

Vperiphery of The several rim sections are constructed with beads orclencher flanges 8 which are adapted to engage the tire cas ing in ,theusual well known manner meeting ends of thev sections 4- and 5 areequipped with hinge members 9 and .10 through which a pintle or hingepin'llf is inserted to -h'ingedly connect the said. sec-.

tions, and the opposite ends of the said seo tions are connected in asimilar manner to. the meeting ends'of the sections 'a'iid 7respectively. -The severalV hinges will be seated in suitably shapedrecesses provided' therefor inth-efelly ofthewlieeliso that the riin`may rest j directly a'ggmst the outer *theA wheel will be prevented.

The, f

thel fellyand`therebyfirmly support the tiie. The section 5 is formed leupon irs inner surface adapted to cn-4 gage a suitably shaped recess ornotch in the felly whereby creeping of the riin about It will be readilyunderstood that thehinges connect-` ing these tioiis 4 and 5 to eachother and to the sections G and 7 respectively, are ordinary abuttinghinges so that the n'ieeting ends of the riiii sections iiiay squirrel)vabut and there will consequentl)1 be no open space' between theV rimsections to pinch or injure the tire casing or tube.

The meeting ends of the sections G and 7 carryupon the, outer surfacesof theflanges 8 hinge pl ites or brackets 1G4 to which are vpivotally 4coiinected `the ends of links 15 so when it in the .rack or when it isbeing'- 'la eiited Man-20, 191 7.,'

Upon the sectioii,[.-pivota lever or keeper 1S, one end A'of which is offset seas to'project over the adjacent end of theV lockingp'la-te 17,.
